This paper discusses the results of an experimental study aimed at evaluating influence vertical ground motion component on seismic performance unreinforced brick-masonry buildings. The research was motivated by post-earthquake observations significant structural damage in vicinity fault, where horizontal and motions are often strong synchronized. Vertical accelerations can fluctuate gravity lo...

Abstract Modeling the seismic response of historical masonry buildings is challenging due to many aleatory and epistemic uncertainties. Additionally, interaction between structural units further complicates predictions behavior unreinforced aggregates found throughout European city centers. This motivated experimental campaign on half-scale, double-leaf stone within SERA (Seismology Earthquake ...

A full-scale seven-story reinforced concrete shear wall building structure was tested on the UCSDNEES shake table in the period October 2005–January 2006. The shake table tests were designed so as to damage the building progressively through several historical seismic motions reproduced on the shake table. A sensitivitybased finite element (FE) model updating method was used to identify damage ...

Introduction: Seismic damage affecting the non-structural components of buildings (such as infills) can significantly impact expected economic losses over a structure’s service life. Recently, autoclaved aerated concrete (AAC) infills have gained attention in construction industry due to their light weight, energy efficiency, and durability. Methods: This study investigates out-of-plane behavio...

Abstract In recent years, the growing need for reducing non-structural damage after earthquakes has stimulated a dedicated effort to develop innovative types of fasteners anchoring components (NSCs) reinforced concrete (RC) host-structures. To contribute such need, and building on previous research, this paper presents results series uni-directional shake-table tests simulated NSCs anchored via...

We describe a method to impose constraints in a molecular dynamics simulation. A technique developed to solve the special case of a linear topology (MILC SHAKE) is hybridized with the SHAKE algorithm. The methodology, which we term MILC-hybridized SHAKE (or MILCH SHAKE), applies to more complex topologies. Here we consider the important case of all atom models of alkanes. Exploiting the mass di...
